Fold optics path: an improvement for an atomic fountain

doi:10.1088/1674-1056/20/8/089501

Abstract A fold optical path is utilized to capture and launch atoms in the atomic fountain. This improved technique reduces the laser power needed by 60 percent, facilitates suppression of the laser power fluctuations, and leads to a more simple and stable system.

Keywords: fold optics path atomic fountain laser power
